AUXILIARY SPRING ATTACHMENT non srarne BED Bo'rroM's;

Application-filed November 1 7, 1922. Serial No. 601,627.

To all whom it may, concern I Be it known that I, SAMUEL RosnfIBLooM,

a citizen of Lithuania, residing at Lowell, in

the county of Middlesex and State of Massachusetts, have inventedcertain new and useful Improvements in Auxiliary Spring Attachments forSpring Bed Bottoms, of

which the following is a specification My invention relatesto auxiliaryspring attachments for spring bedbottoms. It may be used with metal bedsto which woven wire bed bottoms are directly attached or to any type ofbeds wherein the main springs are removable from the bed frame.

I It may also be used with the type of spring bed bottoms whereinhelical springs extend from head to foot.

lVhere these types of bed springs are used there is a tendency to saginthe middle where the weight comes, and this tendency increases withuse as the springs stretch and become weaker.

My attachment is entirely separate from the bed and main springs, and isintended to be sold separately and is of such construct-ion that thepurchaser can readily put it in place in such position that it will bestcounteract thesagging of the main springs. It can also be adjusted tosome extent vertically and is also arranged, so that when anyone sits onthe side of the bed, auxiliary springs allow. of giving thus relievingthe helical springs. I I

These auxiliary springs help to equalize any sudden shock, and help toabsorb it without disturbing the other part'of the bed. By their use twopersons of different I l l holes 40,. bolts 44 and nuts 45,'these dogsweights can sleep in the same bed without inconveniencing each other Inthe drawings, Figure 1 is a plan view of a metal bedstead of -well knownconstruction with the head board and foot board cut oif and mattressremoved toexpose removable springs of a well known .type where the bodof the spring is made of crossed wires wit tension springs at each end.

Fig. 2 is a bottom View of my auxiliary spring attachment removed fromthe bed,

Fig; 4 is a side elevation showing part of a bed'fraine with mydevice'in position. Fig, 5 isa detail sectional elevation showing one ofthe dogs and supports on a larger scale than shown in Fig. 3. i i

F ig. 6 is a detail sectional elevation show- 16,16, 16, side rails 10,11, and the usual cross bars 14 and 15 at the head and foot.

' The main spring bed bottom is represented by B and'includes sidebars20' and 21,

ing the adjusting and nut for one of the shown as of the common tubulartype with the connecting head bar 22 and foot bar 23. The woven fabric246s of a well known type and 1s elastically connected with thehead barand foot bar by tension springs 25. The

bed andsprin s are of a well known type;

My device, indicated generally by C, includes'parallel spacing bars 30and31 havmg a guide rod hole 32 extending vertically througheach barnear each end and having an adjusting slot 35 also located near the endof each bar. These bars are shown as being preferably formed of metalangle irons to secure rigidity.

Bars 30 and 31 are supported at each end a supporting D having boltholes 40, 40 through which pass "adjusting bolts 44:, 44 on the end ofwhich are winged nuts 15, as shown in Figfd. By means of slot 35 can beslid in and outas shownby the dotted lines in Fig. 5 forgconv enience'inadjusting in position. I i k Each d'og ha's a lower jaw 41 and an upperjaw 42 which latter preferably terminates the bed A in case the mainspringsB are removable. Inany exentthejaws 41 and in a nose 43 whi'ch,when in position, extends over andre'sts upon aside rail 10 or 11 of 42fit around .a side 'bar 20 or 21 and hold my attachment in the desiredposition.

'I may use in connection with "each dog a setscrw v416'whichpasses"through one of the 'jaws and bears again'st a barQO or 21 wherebymydevice can be shipped with the I main springs and held firmly inposition against sliding. I

it represents a rigid bottom frame comprising side members 50, 51 andfront and loackmembers 52 and 55, connected at the corners by braces 54to make it rigid.

Through this frame are rod holes 55, 55, 55, y

55 Which register with the guide rod holes 32, 32, 32, 32 in the bars 30and 31.

Extending down through each rod hole 55 is an adjustable guide rod 81 onwhich are clamping nuts 82 and 83, thence down through a hole 32, eachsuch rod being adjustably held in position extending down from frame Eby adjusting nuts 82 and 83 and. 'by winged nut 84L.

Preferably, surrounding each rod is an auxiliary compression spring 80.These springs 80 tend to keep my device up against the bed bottom but itcan readily be lowered against these springs or raised by screwing up ordown nut 84.

F represents the top frame which may be rigid or, preferably,semi-rigid. It is shown as formed by means of a relatively heavyrectangular wire 60, between thesides ofwhich extend the lighter wires61 to hold it from distorting. The helical springs 70, 70 are carried bythebottom frame E and support the top frame F, being attached to wiresand 61 in such manner that they will not tear the mattress.

Preferably, they are so positioned and arranged as to form ahollowrectangle whereby a. substantial space of perhaps six to twelve inchesis left between the front and back rows 71, 72, while the side rows arefilled in by springs 73, 74.

The effect of this arrangement is to stiffen up the sides of the bed butto leave a relatively soft but firm section between 71 and 72.

I prefer to bend up the .wire 60 of top frame F at each side, as shownin Figs. 4

and 5, to holdat 90 and 91 mattress M in position, and to use connectingwires, such as 92, to maintain the rigidity.

To put in place, the dogs D on one side may be slid back-and the devicepushed up from under'the bed, or, slid in between fabric B and a bar 20or 21, and the dogs slid out to engage said bars where they can beclamped in position by nuts 45.

In Figs. 7, I show how a modification of my structure can be used aswith a bed in which the side rails, such as 10 and 11, and side bars.such as 20 and 21, are combined as in a tubular side bar such as S.

In this case, I make the dogs, such as 105,.

- and horizontal weblOl with a rod hole 102.

The dog 105 has only an upper jaw and simply rests on bar S.

.E represents the bottom frame with a member 53 the same as in the otherconstlllCtlOIl, and with a rod hole 55 through which passes a rod 106which also passes through rod hole 102. j

As shown, there are two clamping nuts 82 and 83 to hold it rigidly toframe E and two clamping nuts 105 and 10 1 to hold it rigidly to thespacing bar P.

I claim: 7

1. The combination with a bed having side rails and a spring bed bottomhaving side bars, of an auxiliary spring attachment including parallelspacing bars having guide rod holes and adjusting slots, supporting dogsslidable on said spacing bars and having bolt holes which register withthe adjusting slots and jaws which engage the side bars,

the upper jaw having a nose which engages 'a side rail, adjusting boltswhich pass as to form a hollow rectangle.

' 2. The combination with a bed having side rails and a spring bedbottom having side bars, of an auxiliary spring attachment includingparallel spacing bars having guide rod holes and adjustingslots,supporting dogs slidable on said spacing bars and having boltholes which register with the adjusting slots and jaws which engage theside bars, the upper jaw having a nose which engages a side rail.adjusting bolts which pass through said bolt holes and adjusting slots,winged nuts for said adjusting bolts, adjustable guide rods which extendfrom the rigid bottom frame downwardly and pass through the rod holes inthe spacing bars,

3. In an auxiliary spring attachment for spring bed bottoms, thecombination of parallel spacing bars having guide rod holes andadjusting slots, with supporting dogs slidable on said bars and havingbolt holes, adjusting bolts which pass through said bolt holes andadjusting slots, winged nuts for said adjusting bolts, a rigid bottomframe having downwardly projecting adjustable guide rods which passthough the rod holes in the spacing bars, winged nuts therefor,auxiliary springs between the spacing bars and bottom frame, a topframe, and helical springs carried by the bottom frame and supportingthe top frame positioned to form a hollow rectangle.

4. In an auxiliary spring attachment for spring bed bottoms, thecombination of parallel spacing bars having guide rod holes, withsupporting dogs on said bars, a rigid bottom frame having downwardlyprojecting adjustable guide rods which pass and bottom frame, a topframe, and helical v springs carried by the bottom frame and supportingthe top frame positioned to form a hollow rectangle. v
